Revert "SDVO: Switch control bus only before DDC access" 

This reverts commit ddedf19f88.

After i2c STOP, control bus will return back to internal
registers. So this brings back to origin code that we switch
to DDC bus before START. But it's ideal to only issue DDC
bus switch after STOP, not before every START, which might eliminate
some complains from SDVO device, that will be another patch later.
